The film, entitled 'Beats Rhymes and Life,' will be competing with 15 other titles in the US Documentary category, and will be screening at the festival, which takes place January 20-30 in Park City, Salt Lake City, Ogden and Sundance, Utah.

Originally titled 'Beats Rhymes and Fights,' the documentary focuses on "the rise and influence of one of the most innovative and influential hip hop bands of all time," as the legendary group reunites for the 2008 Rock the Bells tour, where they "re-discover that their own personal differences may overpower their love for the group, countless, hard-core fans, and its ability to survive the pressures of fame."

Rapaport spent eight months filming the doc, recording over 200 hours of footage of the rap legends Q-Tip, Phife Dawg, Ali Shaheed Muhammad and Jarobi. The film features appearances by Kanye West, Nas and De La Soul, an original score by Stones Throw producer Madlib, whose work has clearly been influenced by the Ummah's production, with a score supervised by Stones Throw honcho Peanut Butter Wolf.

A hip-hop fan and supporter for decades, 'Beats Rhymes and Life' marks Rapaport's first attempt at directing a feature. As an actor, he has appeared in dozens of films, including John Singleton's 'Higher Learning' and 'Poetic Justice,' and cult classics like 'Zebrahead,' 'True Romance' and 'The Basketball Diaries.'
